Caution
This film uses a small amount of caustic paste. If any paste appears, avoid contact with skin, eyes and mouth
and keep away from children and animals. If you get some paste on your skin, wipe it off immediately, then
wash with water to avoid an alkali burn. If eye contact occurs, quickly wash the area with plenty of water and
see a doctor. Do not cut or take apart pictures or battery. Do not burn battery or allow metal to touch terminals.

Reciprocity law failure
A wide range of shutter speeds can be used without loss of film speed
or requirements for color filtration. For longer exposure times, some
exposure compensation and filtration is suggested.
Reciprocity

constant manner to a constant exposure
(light intensity x time).
